Description

Song accompaniment system

The present invention relates to a song accompaniment system, and more particularly, to a song accompaniment system capable of sharing audio and / or video data through a communication port.

Initially, the first-generation song half cycle is largely divided into a central processing unit that controls the overall operation of the song accompaniment system according to the contents of a control program stored in the system memory, and voice data such as MIDI (Musical Instrument). Digital Interface) includes a sound generator for generating data, a video generator for generating images, and the like.

In this song accompaniment, the MIDI data for each song stored in the voice generator was not so large that hundreds or thousands of songs could be stored in a storage medium such as mask ROM. We could add new song by attaching to.

However, the background image for the entertainment is to use the image stored on a separately prepared VCR tape or laser disk or the still image stored on the hard disk, and since the background image is not related to the contents of the song, the user quickly becomes uneasy. It became.

The second-generation song half-cycle designed to compensate for these shortcomings supports chorus voice functions to adjust the pitch of the song or the song that the user sings with the choir. The chorus voice function also generates chorus and humming effects in the middle of a song as the user sings. Therefore, the user falls into the illusion of singing a song with an orchestra or choir, and even if the user tunes to the pitch, the user's interest is further enhanced. Although such chorus audio data is not image data, its data amount is very large. For example, the amount of MIDI data for each song is only a few hundred Kbytes, while the chorus voice data occupies several Mbytes even if MPEG or AC-3 compression is used.

Since the chorus voice is thoroughly related to the song, the amount of chorus voice data stored in the storage medium is proportional to the number of songs. Therefore, the capacity of the storage medium for storing chorus voice data has also been enormous.

In addition, since the amount of chorus voice data is very large, only a few songs can be stored in the storage medium such as an expensive mask ROM, and the cost of adding chorus voice data corresponding to a newly released song is excessively generated. There was a problem.

The present invention has been created to solve the above problems, by sharing the voice data and / or video data including the chorus voice data through the communication port can reduce the overall configuration, thereby reducing the installation cost The purpose is to provide a song accompaniment system.

Is sent. The main central processing unit 110 then drives the audio generating device 120 and / or the main video generating device 150 to generate audio and / or video data corresponding to the selection signal. The generated audio and / or video data is transmitted to the terminal half period 200 through the first and second communication ports 160 and 260 again. The terminal half period 200 mixes the user's voice data and the audio data including the transmitted mid and chorus voices and reproduces them through the speaker 275. The transmitted image data and the terminal half period video data are monitored 246. Play through. At this time, even when a plurality of terminal board period 200 is used at the same time, the data communication can be stably performed by the timer 336 without data collision.
